Use these body measurements as a guide to select the size that's right for you. Our tees are designed with a relaxed fit that runs true to size. If you are at the lower end of a size range, expect a looser feel, in the middle the fit will be balanced, and at the top end it may feel more fitted.

How to Measure
  1. Chest Measurement
    Measure around the fullest part of the chest area and keep tape level under your arms and across your back.
  2. Waist Size
    Measure your natural waistline by placing the tape around the narrowest part of your torso, typically just above your belly button.
  3. Garment Length
    For accurate garment length, measure from the top of your shoulder down to where you want the hem to fall.
  4. Sleeve Measurement
    Start at the center of the back of your neck, run the tape across your shoulder, and down to your wrist with arm straight for a full sleeve measurement.

Legendary Comfort™

That soft, all-day feel you never want to take off—now in the t-shirt you reach for without thinking. Built to hold up for years, but somehow still feels like day one. You’ve worn it enough to know: no other tee in your closet even comes close.

Official Non-Profit Partnership

A portion of net proceeds from the sale of this product benefits COSI, sparking curiosity and learning through hands‑on science exploration.

Sizing

Our t-shirt is designed with a relaxed fit that runs true to size. It's made from a soft cotton blend that may shrink slightly after washing, so we recommend washing cold and tumble drying on low to help maintain the fit. Check the Size Guide for fit tips.
